If a calculation was correct before casting out, casting out on both sides will preserve correctness. However, it is possible that two previously unequal integers will be identical modulo 9 (on average, a ninth of the time). The operation does not work on fractions, since a given fractional number does not have a unique representation.
A logarithmic chart allows only positive values to be plotted. A square root scale chart cannot show negative values. x: the x-values as a comma-separated list, for dates and time see remark in xType and yType; y or y1, y2, …: the y-values for one or several data series, respectively. For pie charts y2 denotes the radius of the corresponding ...

Casting out nines is a quick way of testing the calculations of sums, differences, products, and quotients of integers in decimal, a method known as long ago as the 12th century. [ 3 ] 9 is the only square number that is the sum of two consecutive, positive cubes: 3 2 = 9 = 1 3 + 2 3 {\displaystyle 3^{2}=9=1^{3}+2^{3}} [ 4 ]
Rule of nines or rule of nine may refer to: Rule of nine (linguistics), an orthographic rule of the Ukrainian language. Rule of nines (mathematics), a test for divisibility by 9 involving summing the decimal digits of a number; Wallace rule of nines, used to determine the percentage of total body surface area affected when assessing burn injuries

1 troy ounce of four nines fine gold (999.9) Nines are an informal logarithmic notation for proportions very near to one or, equivalently, percentages very near 100%. Put simply, "nines" are the number of consecutive nines in a percentage such as 99% (two nines) [1] or a decimal fraction such as 0.999 (three nines).
A sequence of six consecutive nines occurs in the decimal representation of the number pi (π), starting at the 762nd decimal place. [ 1 ] [ 2 ] It has become famous because of the mathematical coincidence , and because of the idea that one could memorize the digits of π up to that point, and then suggest that π is rational .
